Standard Alumina (74%, 95%, 96%, 98%)

Aluminum Oxide, or alumina, is the most common technical ceramic material used today. The versatility of alumina stems from its broadly impressive material properties, ease of manufacture, wide availability, and budget-friendly cost. STC produces a range of alumina purity from 74% alumina to 99.96% alumina - these bodies are the industry work-horse materials for applications that require electrical isolation, wear resistance, high temperature resistance, and good mechanical strength.

Note: The information in this data sheet is for design guidance only. STC does not warrant this data as absolute values. Forming methods and specific geometry could affect properties. Slight adjustments can be made to some of the properties to accommodate specific customer requirements. Most of the dense materials in the table are resistant to mechanical erosion and chemical attack. STC has performed ASTM testing qualification for certain compositions, in accordance with ASTM D2442. Please consult our technical staff for appropriate material and specific test results.
